Transcribed Image Text:**The Relationship Between Rainfall and Cotton Yield**
The yield of cotton appears to be sensitive to rainfall. An agricultural experiment station collected the following records about June rainfall and yield of cotton. Is cotton yield impacted by rainfall?
| June Rainfall (cm) | Yield (lb/acre) |
|--------------------|-----------------|
| 3 | 1120 |
| 6 | 1750 |
| 7 | 1940 |
| 9 | 2130 |
| 11 | 2380 |
| 15 | 2650 |
| 17 | 2990 |
| 19 | 3130 |
**Task:**
b. Perform a regression analysis. Define your hypothesis, state your conclusions, and show all work.
**Analysis Explanation:**
In this table, we are examining the relationship between June rainfall (measured in centimeters) and the yield of cotton (measured in pounds per acre). You can observe that as rainfall increases, the yield of cotton also tends to increase. To explore this relationship further, a regression analysis can be performed.
1. **Hypothesis:**
- Null Hypothesis (H0): There is no significant relationship between June rainfall and cotton yield.
- Alternative Hypothesis (H1): There is a significant positive relationship between June rainfall and cotton yield.
2. **Steps for Regression Analysis:**
- Compute the regression line using the formula for linear regression.
- Analyze the regression coefficient to determine the nature of the relationship.
- Conduct hypothesis testing to confirm or reject the null hypothesis.
- Evaluate the R-squared value to assess the strength of the relationship.
3. **Conclusion:**
- Based on the regression analysis, draw conclusions regarding the impact of rainfall on cotton yield.
- If the data indicates a strong positive correlation, additional insights on farming practices and irrigation could be explored to maximize cotton yield.
By following these steps, students can understand how statistical tools are applied to real-world agricultural data and contribute to better crop management strategies.
